Question: A nozzle is designed to expand air from a chamber in which the pressure and temperature are 800 kPa and 40°C, respectively, to Mach 2.5. The throat area of this nozzle is to be 0.05 m2. Find
a. The exit area of the nozzle
b. The mass flow rate through the nozzle when operating at design conditions
c. The back-pressure at which there will be a normal shock wave on the exit plane of the nozzle
d. The range of back-pressures over which there will be a normal shock wave in the nozzle
e. The range of back-pressures over which oblique shock waves will occur outside the nozzle
f. The range of back-pressures over which expansion waves will occur outside the nozzle.
